Abstract

In the season 2019, the seed dressing quality of winter wheat and winter barley was tested based on 138 samples with regard to seed dressing dust abrasion and abrasion of active substances. The tests were carried out accord­ing to the Heubach method in a partially adjusted version for the subsequent determination of active substances in the floating dust. It was shown that, with the exception of two samples, all measurements were below the required limit values. For all samples coated with products for which a maximum abrasion of 200 mg active substances per ha (180 kg seeds) is required by German authorities values were below this threshold.
